Method for Transmitting and Receiving Uplink Sounding Reference Signal, Base Station and Mobile Terminal
First Claim
1. A method for receiving uplink sounding reference signals, comprising:
- receiving uplink Sounding Reference Signals, SRSs, transmitted from radio frequency transmission modules of a mobile terminal according to respective Transmission Comb, TC, values and Cyclic Shift, CS, values assigned for the radio frequency transmission modules upon arrival of a transmission cycle, wherein any two of the radio frequency transmission modules are assigned with different TC values and/or different CS values; and
determining, from the respective TC values and CS values assigned for the radio frequency transmission modules, one of the radio frequency transmission modules corresponding to each of the received SRSs.

Abstract
The field of wireless communications is related, especially the technique of transmitting uplink sounding reference signal (SRS) by a mobile terminal with multiple transmission antennas is related. A method for receiving uplink sounding reference signal includes the following steps: receiving the SRS signals, which are respectively transmitted from respective radio frequency transmission modules of the mobile terminal according to the respectively allocated Transmission Comb (TC) values and Cyclic Shift (CS) values when the transmission period arrives, wherein TC values and/or CS values allocated for any two radio frequency transmission modules are different; determining the radio frequency transmission module corresponding to every received SRS signal according to the TC values and CS values respectively allocated for respective radio frequency transmission modules. A device for receiving uplink sounding reference signal, a method and a device for transmitting uplink sounding reference signal are also provided. Because different TC values and/or different CS values are allocated for respective radio frequency transmission modules, (multiple) radio frequency transmission modules can transmit SRS signals through (multiple) transmission antennas during the same transmission period by way of Frequency Division Multiplex (FDM) or Code Division Multiplex (CDM).
